The present invention relates to a
novel technique-
colloidal gold immunochromatography for quickly detecting the Swine Hemagglutinating
encephalomyelitis virus (HEV), and to a test paper which is prepared by the technique for preparing the Swine Hemagglutinating
encephalomyelitis virus. The invention develops a
monoclonal antibody (Ab1) of the Swine Hemagglutinating
encephalomyelitis virus and a
monoclonal antibody (Ab2) of rabbit anti- Swine Hemagglutinating encephalomyelitis virus. The Ab1 labeled
colloidal gold is taken as the gold-labeled
antibody and the Ab2 is taken as the catching antibody. The normal anti-mouse IgG antibody is used as a
quality control antibody. The materials of antibody,
cellulose nitrate film (NC film), combining pad, sample pad, back lining, plastic card, etc. are processed and assembled to the test paper. The test paper can detect the Swine Hemagglutinating encephalomyelitis virus in the sickened
pig brain tissue and the
feces. The technique of the invention has the characteristics of simple operation, high speed, excellent sensitivity, excellent specificity, etc. Furthermore the technique of the invention is especially suitable for the clinic sample detection of
disease appearance field, clinic, places with no available experiment condition, etc.
